Northwest To Stay Active and Frigid Through The Weekend
A strong cold front will usher in big changes for the Northwest starting on Thursday, as a good, soaking rainfall looks to push into the I-5 corridor starting on Thursday afternoon and lasting through Thursday night and into Friday morning. Snow levels are expected, via the National Weather Service in Seattle, to range from 4500 feet in the northern Cascades to 6000 feet further south, borderline for pass levels.
A brief break should keep things relatively dry (though grey) for both Seattle and Portland, Oregon for Friday and early Saturday, but more rain with a second, warmer system arrives on Saturday night, and with it more moisture. Snow levels will be higher for this system than Thursday’s storm. By Monday, drier air works in after the soggy weekend.
Rain totals along the coast over the next four days should be in the 1-2″ range, while localized amounts of 3-5″ in favored locations, such as west-facing slopes of Washington’s Olympic Mountains, are also likely. Localized flooding could occur in areas that receive the highest rainfall.
After receiving over 11 inches above its typical annual average in 2014, January has started off on the dry side for the Emerald City, with just over an inch (1.08″) of rainfall recorded at Seattle-Tacoma International Airport so far this month.
